The spreadsheet has a graphical interface, and graphical rendering is required when displaying, printing or exporting, and the adaptation of the spreadsheet graphical rendering to different display screens and different export formats needs to be considered. Some of these different display devices are processed in a similar manner, and some of them are processed in a different manner.
For display devices with similar processing modes, such as rendering to a screen and exporting as PDF, drawing on a canvas can be considered, but the APIs called by the display devices are different. In the prior art, standard APIs are established, and each device can realize the APIs, and then the APIs are called uniformly, so that differences can be shielded, and the workload is reduced. However, in the output form, all elements are drawn on one canvas in the form of layers, and the elements must be processed in place at one time, cannot be processed in stages, cannot be adjusted at the later stage, and the whole canvas must be redrawn when any layer is modified.

It is to be understood that the embodiments described are only a few embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Some of the techniques involved in the embodiments of the present application are described below to aid in understanding, and they should be considered merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the present application. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
Fig. 1 is a flowchart of a method for implementing drawing based on vector primitives according to an embodiment of the present application, including steps 101 to 105. Fig. 1 is only one execution sequence shown in the embodiment of the present application, and does not represent the only execution sequence of the drawing implementation method based on vector primitives, and in the case that the final result can be achieved, the steps shown in fig. 1 may be executed in parallel or in reverse.
Step 101: and acquiring the service object in the output area and determining the type of the service object. Specifically, a first function which can be used for acquiring a service object in an output area is created; wherein the output area includes the entire spreadsheet, a selected piece of area, or a displayed visual interface area. In the embodiment of the present application, IRange range = workschet. Range [ "A1: D10" ] is used to obtain an output area, that is, A1: D10 piece of output area is obtained; the GetRangeDrawing () function is then used to obtain the business objects in the output areas A1: D10 within the function. Types of business objects include, but are not limited to: tables, charts, slices, pictures, graphs. Wherein, getransedrawing () is a first function described in the embodiments of the present application, and getrans Draawing () is only a name for a method in the embodiments of the present application, and is not intended to limit the scope of the embodiments of the present application.
Step 102: a base object in the business object is identified. Specifically, in the embodiment of the present application, the basic objects in the chart include: cell, fill, text, curve, etc. The base objects in the table include: cell, fill, text, etc.
Step 103: the basic elements in the base object are abstracted into basic primitives. Wherein, different basic primitives are located in different image layers.
The specific implementation manner and technical effects of step 103 can refer to the embodiment shown in fig. 2, including steps 201 to 204, which are described in detail as follows.
Step 201: a second function is created for the base object. Wherein the first function may call the second function. Specifically, in the embodiment of the present application, the second function is getcelldraw (), which can be called by the first function getpagedraw (); herein, getCellDrawin () is only a name for the embodiment of the present application, and is not a limitation to the scope of the present application.
Step 202: the base elements in the base object are identified using a second function. Specifically, in the embodiment of the present application, when the base object is a table, the second function can traverse each cell in the table, and obtain information of the row width, the column height, and the like of the cell, so as to calculate the position and the size of the cell. When the basic object is a graph, a picture, a chart and the like, the second function finds out the optimal circumscribed rectangle of the basic object by acquiring the coordinate and the width and height information of the upper left corner of the basic object, judges whether the optimal circumscribed rectangle of the basic object is intersected with the output area or not, if the optimal circumscribed rectangle of the basic object is intersected with the output area, continues to acquire the basic element of the basic object, and otherwise, does not perform processing. The method for obtaining the position and size of other basic objects is similar to the method for obtaining the position and size of cells or graphics, and those skilled in the art can also obtain the position and size of the basic object in other manners, which are not described in detail herein.
Step 203: a drawing function is created from the base element data. Specifically, a drawing function is created for the basic elements in the basic object according to the acquired basic object data.
Step 204: and generating a basic primitive by using a drawing function. Specifically, the drawing function created in step 203 may be used to draw vector primitives, which are referred to as primitives in this application. In the embodiment of the present application, if the basic object is a cell, the basic elements in the cell of the basic object include: character elements, filling elements and frame elements. The second function creates a drawing function from the cell data, comprising: drawing function of text: createTextDrawing () which represents the generation of a character primitive used for drawing a character element; drawing function of the frame: createLineDrawing (), which indicates that line segment primitives are generated, and the border or broken line segment of one cell can be represented by a plurality of line segment primitives; filled drawing function: and the CreateFillDrawing () represents the generation of the filling graphic primitive and is used for filling the closed area formed by the line segment graphic primitive.

The business object comprises a basic object and/or a diagram group and/or a basic diagram element; the group of primitives comprises basic primitives. Through steps 101 to 103, the service object in the output area is decomposed hierarchically and is constructed as a primitive tree as shown in fig. 4, wherein the basic elements are replaced by the abstracted basic primitives, the basic primitives in 404 may form primitive groups, the basic object in 403 may form primitive groups, and the basic primitives may also be used as child nodes to form the service object individually and/or as the basic object. In this embodiment, as shown in fig. 5, where 501 is a root node of the output area primitive tree, 502 is a child node of the primitive tree, 503 is a grandchild node of the primitive tree, and a basic primitive abstracted by a basic element of a basic object in 503 may constitute a primitive group such as 505.
Step 105: and determining the type of the display equipment and calling a corresponding function to output the primitive tree. Specifically, determining the type of the display equipment; wherein the display device types include: display screen, printer, PDF, HTML, picture and SVG; traversing the primitive tree to determine the basic primitive in the primitive tree; and calling a drawing function and an API corresponding to the display equipment, and drawing the primitive tree in the display equipment. In the embodiment of the present application, if the display device is the display 604, 604 shown in fig. 6, controlled by the host 603 and connected to the network 601, the display device is the screen of the display 604, and the PaintToScreen () method in the API is called to draw the primitive tree on the display during output. Similar to 604 input methods, a tablet computer 602 and a portable computer 606 are also included. In addition, the primitive tree can be output in an Html format, a PDF format or an SVG format through the combination of operations 603 and 604 and 606 or 602, and the primitive tree can be drawn as required only by calling different functions PaintToHtml (), paintToPDF () and PaintToSVG () in the API respectively. Because each output device has a fixed drawing function, when the primitive tree in the application is output, each basic primitive in the primitive tree needs to be traversed, a pre-programmed conversion layer function is called, and the basic primitives in the application are converted, so that the drawing of the output device draws each basic primitive in the primitive tree.
Meanwhile, the printer can be connected to print files with different formats. The device used in the embodiments of the present application includes at least the device or module shown in fig. 7.
